Feedback on Mobipast app

I'm looking to install an app called Mobipast (http://mobipast.com/) , but before that, i'd like to have some feedback from people who already know this parental control app (does it work on Iphone (5c)? Do i need to jailbreack or something?)

Anyways, advice and feedback on this type of app. If you know any other like it, please don't hesitate to share.
